Description

2888294 1

  The present invention relates to a device for mixing liquid and gas pressurized by a pump.

BACKGROUND OF THE INVENTION

Description of the prior art

  In the prior art of fish farming, fish are raised in aquariums or fish ponds. An electric gas pump device is used to pump gas therein so that the air can be dissolved in the water and thus the oxygen contained in the water is retained at an acceptable value for the fish .

  However, in the prior art, the air bubbles are too large to have sufficient areas of contact with water, and especially the bubbles rise rapidly so that less air is dissolved in the water. The effect of dissolution is thus smaller and is not sufficient for fish inside aquariums or ponds.

  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 and 2 is illustrated the device for mixing liquid and gas pressurized by a pump, according to the present invention. It includes the following elements.

  It comprises a hollow body 1 having an upper surface. An impermeable hole (not shown) is formed at the top of the hollow body 1. The hollow body forms, from top to bottom, a mixing and suction chamber 11 of gas and liquid and a chamber 12 of dissolution and setting in gas and liquid pressure. At least one connecting opening 13 is formed between the chamber 11 for mixing and suctioning gas and liquid and the chamber 12 for dissolving and pressurizing gas and liquid. An inlet opening 111 of gas and liquid suction is arranged on one side of the chamber 11 suction and mixing gas and liquid near the top thereof. The inlet port 111 for suction of gas and liquid is connected to a conduit 2 for suction of gas and liquid. The gas and liquid suction duct 2 includes a liquid inlet tube 22 and at least one gas inlet tube 21 which communicates with the liquid inlet tube 22. At least one of the liquid inlet tube 22 and said at least one gas inlet tube 21 communicates with an ozone generator 211 (with reference to FIG. 4) or other machine capable of generating other gases. The gas inlet tube 21 may form a body with the liquid inlet tube 22 so that the liquid 32 (for example water) enters the liquid inlet tube 22 and the gas 31 enters. in the tube 21 of gas inlet. Then the liquid 32 and the gas 31 enter the chamber 11 for mixing and suction of gas and liquid 11 through the inlet port 111 for suction of gas and liquid.

  The chamber 12 for dissolving and pressurizing gas and liquid comprises at least one plate 121 for resistance to the flow of gas. A liquid outlet orifice 122 is arranged on one side of the chamber 12 for dissolving and pressurizing gas and liquid, near the bottom of the latter. The liquid outlet port 122 is connected to a conduit which has a constant pressure valve 91 for controlling the flow of liquid.

  The device 1 also comprises a pump 4 with a drive motor comprising an axis 41. The shaft 41 enters the chamber 11 for suction and mixing gas and liquid from the impervious hole 2888294 3 that comprises the hollow body 1. The shaft 41 and the impermeable hole are completely sealed. No gas is formed. A rotary blade 5 is fixed to the axis 41. The rotary blade 5 is placed in correspondence of the inlet orifice 111 for suction of gas and liquid from the chamber 11 for suction and mixing of gas and liquid. A plurality of intersecting slot recesses are formed on the rotary blade 5. On the outside of the motor pump 4 is a housing 42 for protecting the motor pump 4.

  When the motor pump 4 is put into operation, the shaft 41 causes the blade 5 to rotate continuously at high speeds. The liquid 32 and the gas 31 enter the chamber 11 for suction and for mixing gas and liquid through the liquid inlet tube 22 and the gas inlet tube 21 of the liquid suction conduit 2 and gas. In addition, by high speed rotation of the crenellated recesses 51 of the rotary blade 5, the gas and the liquid are agitated so that the gas 31 dissolves in the liquid 32 to generate many small bubbles 71. The small bubbles 71 and the liquid 32 are pressurized by the motor pump 4 and then pass through the connecting opening 13 to enter the chamber 12 for dissolving and pressurizing the gas and the liquid. The flow is retained and is guided by the flow resistance plate 121 installed in the gas and liquid dissolving and pressurizing chamber 12 to increase space and area for receiving gas and liquid. so that the small bubbles 71 have sufficient time for pressurization. As a result, the oxygen (ozone) contained in the liquid 32 is above the saturation value. Then the small bubbles 71 are transferred to any container through the liquid outlet port 122. The container may be, for example, aquariums, fish tanks 61 (with reference to FIG. 3), various kinds of installations 62 for treating toxic waste (with reference to FIGS. 4, 5 and 6) or swimming pools 63 ( with reference to Figure 7), etc. With reference to FIGS. 4, 5 and 6, when the small bubbles 71 are transferred into the container at ambient pressure, the supersaturated oxygen (ozone) escapes from the liquid 32 to form the small bubbles 71. 71 bubbles hit 81 disks, 82 medical instruments, 83 plants, fruits, foods, etc. The oxidation of oxygen (ozone) eliminates the insecticides, pesticides or other germs on these objects so as to ensure the safety in the consumption of food or in the use of utensils. A container, in particular an installation 62 for treating toxic waste, may comprise a rotary blade 92. The rotary blade 92 is driven by a motor 93 placed in the bottom of the container. In this way the small bubbles 71 have a greater impact to hit the objects to have the effect of detoxification and sterilization.

  With reference to FIGS. 3 and 7, if the present invention is used for aquariums or fish tanks 61 (with reference to FIG. 3), or swimming pools 63 (with reference to FIG. 7), oxygen in the Liquid will increase in order to have the effect of detoxification and sterilization to improve the fish growth environment or the users environment.

  The advantages of the present invention are set forth below. When the small bubbles 71 are transferred into the container, at ambient pressure, the supersaturated oxygen (ozone) escapes from the liquid 32 and form a large number of small bubbles 71. The small bubbles 71 collide with the disks 81, medical instruments 82, plants 83, fruits, food, etc. The oxidation of oxygen (ozone) removes insecticides, pesticides or other germs on these objects to ensure safety in the consumption of food or in the use of utensils. Most importantly, if the present invention is used for aquariums, fish ponds 61 (with reference to Figure 3), or swimming pools 63 (with reference to Figure 7), the oxygenated liquid will increase the detoxification and sterilization to improve the fish growth environment or the user environment. The effect of the present invention is rapid and time-saving.
